Description

Primordial non-Gaussanities can provide valuable information about the primordial universe. We explore the possibility of constraining them with photometric galaxy redshift surveys. Further, I will discuss how the inclusion of velocity maps via the kinetic Sunyaev Zeldovich effect can improve the estimator. Finally, I will comment on the prospects of reaching fnl<1 in the future.
